While the descriptions in this book are helpful, the illustrations are inherently imprecise because they are non-photographic. The size of the book is good for taking into the field, but I'm put off by the old-school descriptions of mushrooms that have psychedelic/entheogenic properties. These important fungal allies are dismissed as "hallucinogenic" used by certain people for recreational purposes. Therefore they are labelled poisonous.
Overall, I found that I felt I couldn't trust the book to provide the kind of precision and accuracy that I need to be confident about my identifications. I would say use it as a secondary guide, or for an initial assessment of your fungal findings, but rely on more modern sources that also provide photographs.
